FIELD OF THE INVENTION

The field of the invention relates to transmitters and, morespecifically, to the actuation of appliances using transmitters.

BACKGROUND

Various types of appliances are utilized in today's homes andbusinesses. For example, doorbells, intercoms, lights, fans, alarmsystems, and moveable barrier operators are only a few examples of suchappliances in use today. To activate or control the operation of anappliance, some type of actuator is typically used. For instance, aswitch may be actuated by a user in order to activate a light or adoorbell button may be pressed by a user to cause doorbell chimesassociated with the button to sound. In some examples, the actuator maybe hard-wired to the appliance. In other cases, the actuator may beassociated with a wireless transmitter. When a wireless actuator isactuated, a radio frequency (RF) signal is formed and then transmittedvia an antenna to the appliance. The appliance receives the RF signaland activates the appliance according to the RF signal.

Wireless systems have proved to be convenient for many users, forexample, avoiding the need to re-wire existing systems. Unfortunately,wireless systems also have experienced various problems that oftenlimited their use and/or effectiveness. More specifically, wirelesssystems are often attached to the exterior walls of buildings. The wallsthemselves are constructed of materials such as stucco (that include ametallic mesh), or are surrounded by steel or aluminum siding all ofwhich interfere with and/or absorb wireless signals intended to be sentfrom the wireless transmitters to the appliance. Wireless doorbells orchimes are a good example of the later problem where signals transmittedby wireless doorbell buttons (attached to the exterior walls ofbuildings) often could not be received and/or were interfered with bythe constructional composition and/or structure of the walls to whichthey were attached. Hence, these signals could not be received by thechime unit, or if they were received, were unusable by the chime unitdue to degradation in signal quality.

Moreover, with respect to wireless door chimes, transmitters andbatteries required for the chimes created a unit with less than idealaesthetics. These items extended out from an outside wall as opposed tobeing nearly flush or co-planar with the planar surface of an outsidewall. The outwardly extended portion of the doorbell button unit createda less than desired aesthetic unit when installed.

As a result of the above-mentioned problems, wireless signals sent bywireless actuators which were intended to activate and/or control anappliance often were not received by the appliance. Units also werecreated with less than desired attractiveness to consumers. Theseproblems have led to user inconvenience and frustration with theseprevious systems.

SUMMARY

An apparatus and method are provided whereby portions of a wirelesstransmitter apparatus are arranged and situated so as to ensure that thewireless signals transmitted by the apparatus will be received by aremotely situated appliance and received in a form that is usable by theappliance. More specifically, an antenna of the apparatus is disposed soas to avoid the interference of structural elements of buildings. Inthis regard and to take one example, an opening (e.g., hole) can beformed (e.g., drilled) in a structural element (e.g., wall) of thebuilding, and the antenna extended into or through the opening.Consequently, a transmission from the apparatus to an appliance occurswithout the interference of the structural element of the building andthe signal will be received in a form usable by the appliance. Theapproaches described herein are easy to use, are aesthetically pleasing,can be retrofitted with existing buildings and appliances, and are easyand cost effective to implement.

The apparatus and method described herein include a transmitterapparatus effective for activating a remotely situated appliance. Thetransmitter apparatus includes a transmitter actuator and a radiofrequency (RF) transmitter. The radio frequency (RF) transmitterincludes RF transmission circuitry and an antenna. The RF transmitter isconfigured to be mounted to a structural element of a building andconfigured to receive an actuation by a user to wirelessly transmit asignal. An antenna is coupled to the RF transmitter circuitry and isarranged and configured to transmit the signal to a remotely situatedappliance. The antenna is disposed within an opening in the structuralelement of the building and is of dimensions so as to extend at leastpartially through the opening. The antenna transmits the signal to theappliance without significant interference or absorption from thestructural element of the building.

In some of these examples, the RF transmitter further includes a powersource and the power source is disposed so as to be accessible to theuser without removing the RF transmitter from its mounted position.

The antenna can be also structured in any number of ways. For example,the antenna may be a wire or a printed circuit board (PCB) antenna.Other examples of antennas are possible. When a wire is used, the length(or other characteristics) of the wire may be selected so that the wireextends through the opening and, hence, beyond the structural element ofthe building.

In still others of these examples, the transmitter may include a housingwith the antenna being disposed within the housing. In some examples,the housing is generally cylindrical in shape.

Further, the transmitter and transmitter circuitry may be secured tovarious structural elements of buildings according to the presentapproaches. For example, the transmitter may be secured to exteriorwalls, interior walls, or barriers (e.g., doors). Other structuralelements may also be used.

The remotely situated appliance may also be a variety of differentdevices. For example, the remotely situated appliance may be a doorbell,a light; an intercom, a fan, an alarm system, a moveable barrieroperator, a window treatment, a rolling shutter, a hot tub, a fireplace,a television, or a video source. Other examples of appliances arepossible.

The transmitter may be coupled to a number of different actuators. Forexample, one or more buttons may be included. In some examples, the oneor more buttons are illuminated.

In others of these approaches, a transmitter is mounted to an exteriorsurface of a building and the transmitter including the transmissioncircuitry and the antenna. An opening is formed in the building and theopening extends at least partially through a structural element of thebuilding. The antenna is disposed within the opening. The transmittermay be actuated and responsively transmit a radio frequency (RF) signalto the remotely situated appliance via the antenna. The signal beingtransmitted to the appliance is received at the appliance withoutsignificant interference or absorption from the structural element ofthe building.

The opening may be formed according to a variety of differentapproaches. For example, the opening may be a variety of dimensions,shapes, and sizes, in one example passing completely through a wall ofthe building. In other examples, the opening may only pass partiallythrough the wall. In still other examples, the opening is a preexistingopening in the wall and no new opening need be created.

In some examples, the opening extends completely through the structuralelement of the building and the antenna is disposed so as to completelypass through the opening. In other examples, the hole may extendcompletely through the structural element, but the antenna may extendonly partially through. In still other examples, both the opening andthe antenna extend only partially through the structural element of thebuilding.

Thus, approaches are provided where wireless transmitters can besuccessfully used to activate or otherwise control appliances. Theseapproaches minimize or eliminate the impact of the construction,configuration, or other characteristics of building elements or otherpotential interference sources. The approaches described herein are easyand cost effective to implement, aesthetically pleasing, and result inthe effective operation and/or control of appliances for the user.Consequently, user satisfaction with systems that implement theseapproaches is significantly enhanced.

DESCRIPTION

Referring now to FIG. 1, one example of a wireless transmission systemis described. A transmitter 104 is reactively coupled to an actuator 102to provide a transmitter apparatus 101. In this example, the actuator102 is a button. In other examples, the actuator 102 may be a switch,keypad, or rotating wheel. Other examples of actuators are possible. Inaddition, there may also be more than one actuator 102 (e.g., multiplebuttons). In other examples, the actuator 102 may be illuminated by alight or other arrangement disposed within the actuator 102 or thetransmitter 104. A decorative plate (not shown) may also surround theactuator 102.

An antenna 106 is coupled to the rear of the transmitter 104. Radiofrequency (RF) signals are transmitted from the antenna to an appliance110. The signals are received by the appliance 110 and may activateand/or otherwise control the operation of the appliance 110.

The antenna 106 may be any antenna structure capable of transmittingradio frequency (RF) signals. In one example, the antenna is a stiff orsemi-stiff wire. In other examples, the antenna may be a printed circuitboard (PCB) antenna. Other examples of antenna structures are possible.

The appliance 110 may be any of a variety of types of devices. Forexample, the appliance may be a doorbell (or chime), a light, anintercom, a fan, an alarm system, a moveable barrier operator, a windowtreatment, a rolling shutter, a hot tub, a fireplace, a television, or avideo source. Other examples of appliances are possible. The appliance110 is remotely situated from the actuator 102, transmitter 104, andantenna 106. That is, the appliance 110 is not coextensive with theseelements and is within range of signals transmitted from the antenna106.

As shown, an opening 107 extends completely through a structural element108 of a building. The structural element 108 may be any structuralcomponent of a building such as an external wall, an internal wall, or abarrier (e.g., door, gate, or the like). Other examples of structuralelements are possible. The opening 107 may be formed in any number ofways. For example, a standard drill using a standard drill bit may beused to form the opening (e.g., a hole one inch or less in diameter).Other approaches for forming the opening are possible. In some cases,the opening may be an existing opening.

Additionally, the antenna 106 may be enclosed in a housing (not shown inFIG. 1). In some examples, the housing may be cylindrical in shape andsized to fit into the opening 107. For instance, when a housing is used,the housing may fit in the hole created by standard sized drill bits. Insome cases, the housing advantageously allows the antenna to be placedinto and/or through the opening 107 without snagging the antenna 106.

The transmitter 104 may include circuitry 105 to receive an actuationfrom the actuator 102 and convert the actuation into a signal fortransmission via the antenna 106. The transmitter 104 and transmittercircuitry 105 are secured to the structural element 108 and the antenna106 is disposed within the opening 107 (e.g., a drilled hole) in thestructural element 108 of a building. In so doing, any interference orabsorption of RF signals transmitted by the antenna 106 caused by thestructural element 108 of the building (or items attached to orassociated with the structural element 108) is substantially reduced oreliminated. In other words, this configuration allows a signal ofsufficient quality (e.g., having a sufficient power level or otheroperating characteristics) to be received and recognized by theappliance 110.

The transmitter 104 may further include and is coupled to a power source114. In some examples, the power source 114 is a battery. The powersource 114 is disposed so as to be accessible to the user withoutremoving the transmitter 104 from its mounted position. For example, thepower source 114 may be accessed by a removable cover. In otherexamples, the power source 114 is only accessible by the transmitterfrom its mounted position. For example, the whole of the transmitter 104may need to be removed before the power source 114 can be accessed.

Referring now to FIG. 2, another example of a wireless transmissionsystem is described. A transmitter 204 including circuitry 205 andantenna 206 are coupled to actuator 202. In this example, the actuator202 is a button. In other examples, the actuator 202 may be a switch,keypad, or rotating wheel. Other examples of actuators are possible. Inaddition, there may also be more than one actuator 202 (e.g., multiplebuttons). In other examples, the actuator 202 may be illuminated by alight or other arrangement disposed within the actuator 202 or thetransmitter 204. A decorative plate (not shown) may also surround theactuator 202.

An antenna 206 is coupled to the rear of the transmitter circuitry 205.Signals are transmitted from the antenna to an appliance 210. Radiofrequency (RF) signals are received by the appliance 210 and mayactivate and/or otherwise control the operation of the appliance 210.

The antenna 206 may be any antenna structure capable of transmittingradio frequency (RF) signals. In one example, the antenna is a stiff orsemi-stiff wire. In other examples, the antenna may be a printed circuitboard (PCB) antenna. Other examples of antenna structures are possible.

The appliance 210 may be a variety of type of devices. For example, theappliance may be a doorbell (or chime), an intercom, a light, a fan, analarm system, a moveable barrier operator, a window treatment, a rollingshutter, a hot tub, a fireplace, a television, or a video source. Otherexamples of appliances are possible. The appliance 210 is remotelysituated from the actuator 202, transmitter 204, and antenna 206. Thatis, the appliance 210 is not coextensive with these elements and iswithin range of signals transmitted from the antenna 206.

As shown, an opening 207 extends partially through a structural element208 of a building. The structural element 208 may be any structuralcomponent of a building such as an external wall, an internal wall, or abarrier (e.g., door, gate, or the like). Other examples of structuralelements are possible. The opening 207 may be formed in any number ofways. For example, a standard drill using a standard drill bit may beused to form the opening (e.g., hole one inch or less in diameter).Other approaches for forming the opening are possible. In some cases,the opening may be an existing opening.

Additionally, the antenna 206 may be enclosed in a housing (not shown inFIG. 2). In some examples, the housing may be cylindrical orrectangular, or other shape which is sized to fit into the opening 207.For instance, when a housing is used, the housing may fit in the holecreated by standard sized drill bits. In some cases, the housingadvantageously allows the antenna to be placed into and/or through theopening 207 without snagging the antenna 206.

The transmitter 204 includes circuitry 205 to receive an actuation fromthe actuator 202 and convert the actuation into a signal fortransmission via the antenna 206. The transmitter 204 is secured to thestructural element 208 and the antenna 206 is disposed within theopening 207 (e.g., a drilled hole) in the structural element 208 of abuilding. In this example, the antenna 206 does not extend completelythrough the structural element 208. However, in this example thisplacement is acceptable due to the construction and structure of thestructural element 208. For instance, steel or aluminum siding may bepresent on only one side of the structural element 208 and once theantenna 206 extends beyond this siding, any interference or absorptionproblems are significantly reduced or eliminated. In other words, asignal of sufficient quality (e.g., having a sufficient power level orother operating characteristics) is received and recognized.

The transmitter 204 is coupled to a power source 214. In some examples,the power source 214 is a battery. The power source 214 is disposed soas to be accessible to the user without removing the transmitter 204from its mounted position. For example, the power source 214 may beaccessed by a removable cover. In other examples, the power source 214is only accessible by the transmitter from its mounted position. Forexample, the whole of the transmitter 204 may need to be removed beforethe power source 214 can be accessed.

Referring now to FIG. 3, the placement of a wireless transmission systemis described. In this example, the transmitter apparatus which includestransmitter 302 (with an actuator 304) is attached to the surface of awall 306. An antenna of the transmitter (not shown) extends through ahole in the wall 306 to the other side of the wall 306. In so doing, anyinterference or absorption of RF signals transmitted by the antennacaused by the wall or items attached to or associated with the wall orstructural element (e.g., siding, other electronic devices) issubstantially reduced or eliminated.

Referring now to FIG. 4, an example of a wireless transmission system isdescribed. A transmitter 402 includes an actuator 406 and an antenna404. In this example, the antenna 404 is a wire. The transmitter 402includes circuitry to receive an actuation from the actuator 406 andconvert the actuation into a signal for transmission via the antenna404. A removable cover 407 is removed to access a power source (e.g., abattery).

The transmitter 402 is secured to a wall and the antenna 404 is disposedwithin an opening (e.g., a drilled hole) in a structural element (e.g.,a wall) of a building. In some examples, the opening extends completelythrough the structural element and the wire is of suitable length so asto extend completely through and out of the opening. In so doing, anyinterference or absorption of RF signals transmitted by the antenna 404caused by the structural element of the building (or items attached toor associated with the structural element) is substantially reduced oreliminated.

Referring now to FIG. 5, another example of a transmission system isdescribed. A transmitter apparatus includes transmitter 502 with itscircuitry (not shown), an antenna and an actuator 506. In this example,the antenna 504 is a wire. The antenna 504 is housed in a housing 505.The housing is constructed of a suitable material such as a rigidplastic that does not interfere with or minimally interferes withtransmissions made via the antenna 504. A removable cover 507 is removedto access a power source (e.g., a battery). In some examples, thehousing 505 is cylindrically shaped and fits within a predrilled hole inthe structural element (e.g., wall) of a building. The dimensions of thehousing (e.g., its diameter) in some examples are such that it fitswithin a hole drilled with standard drill bits. In some instances, thehousing 505 may advantageously be inserted into the drilled hole withouthaving the antenna 504 snag on or otherwise be encumbered by the sidesof the hole.

The transmitter 502 includes circuitry to receive an actuation from theactuator 506 and convert the actuation into a signal for transmissionvia the antenna 504. The transmitter 502 is secured to a wall and theantenna 504 is disposed within an opening (e.g., a drilled hole) in astructural element (e.g., a wall) of a building. In some examples, theopening extends completely through the structural element and the wireis of suitable length so as to extend completely through and out of theopening. In so doing, any interference or absorption of RF signalstransmitted by the antenna 504 caused by the structural element of thebuilding (or items attached to or associated with the structuralelement) is substantially reduced or eliminated.

Thus, approaches are provided whereby portions of a wireless transmitterare arranged and situated so as to ensure that the wireless signalstransmitted by the transmitter will be received by an appliance intendedto receive the wireless signals. More specifically, an antenna portionof the transmitter is disposed so as to avoid, reduce, or eliminate theinterference of structural elements of buildings. The approachesdescribed herein are easy to use, can be retrofitted with existingbuildings and appliances, and are easy and cost effective to implement.
